I've tried several other magnesium and malic acid supplements for my fibromyalgia pain and fatigue, and none of them really felt like they were doing anything for me. After having two weeks of the worst flare-up I'd had in several months, I decided to start taking this. Within one day, my pain had reduced significantly. By the second day, I felt even less pain and started to feel less tired when standing. After about a week, I am still noticing a marked reduction in pain and muscle fatigue.
What's more, after several months of having pretty severe bladder control issues, I found they were completely gone after taking this product. I'd heard magnesium was good for bladder control, but I'd never experienced relief this quickly with any other product.

I've been taking this product for a couple of years on the advice of my doctor to increase my energy level. It has helped, so I'll continue to take it. Thank you iHerb for your excellent service and reasonable prices.

I have taken magnesium from another supplier and was much happier with it. Wish I had known that the tablet was so large. I can't get the four suggested down each day. Lucky if I get one down. I can't order tablet this large.
